Thanks guys.
Just as an update - I have installed the pipe using the flex-couplings. I tried to use the standard slip-couplings but had severe trouble getting them to 'slip'.
Anyway - it all looks fine now. I am just paranoid that there is a leak potential. Is it normal to test the system...
Thanks for advice - whats a slip coupling. I have found a short length coupling with a seal both ends - is this one?
That was what I was going to use anyway?!?!
cheers
I am trying to connect a new downstairs toilet into the vertical downpipe. I have exposed the downpipe, and am about to dig into the concrete flooring to get enough length to cut out a section and replace it with the appropriate connection. It seems that they have their own seal and simply slide...
